| 2 | Endoscopic resection of colorectal granular cell tumors显示文摘AIM: To determine the feasibility and effectiveness of endoscopic resection for the treatment of colorectal granular cell tumors(GCTs). METHODS: This was a retrospective study performed at a single institution. From January 2008 to April 2015, we examined a total of 11 lesions in 11 patients who were treated by an endoscopic procedure for colorectal GCTs in the Endoscopy Center, Zhongshan hospital of Fudan University, Shanghai, China. Either endoscopic mucosal resection or endoscopic submucosal dissection(ESD) was performed by three surgeons with expertise in endoscopic treatment. The pre- and postoperative condition and follow-up of these patients were evaluated by colonoscopy and endoscopic ultrasonography(EUS).RESULTS: Of these 11 lesions, 2 were located in the cecum, 3 were in the ileocecal junction, 5 were in the ascending colon, and 1 was in the rectum. The median maximum diameter of the tumors was 0.81 cm(range 0.4-1.2 cm). The en bloc rate was 100%, and the complete resection rate was 90.9%(10/11). postoperative pathology in one patient showed a tumor at the cauterization margin. however, during ESD, this lesion was removed en bloc, and no tumor tissue was seen in the wound. No perforations or delayed perforations were observed and emergency surgery was not required for complications. All patients were followed up to May 2015, and none had recurrence, metastasis, or complaints of discomfort.CONCLUSION: Endoscopic treatment performed by endoscopists with sufficient experience appears to be feasible and effective for colorectal GCTs. | Iri Take Qiang Shi Zhi-peng Qi Shi-lun Cai li-Qing Yao ping-hong Zhou Yun-Shi Zhong | 2015 | World Journal of Gastroenterology2015，21，48： | 2 |
